There is no doubt the Canon EOS R3 is going to be announced soon. We…
A pro EOS R model with a hybrid EF/RF lens mount is rumored over the web.
It’s suggested the upcoming pro EOS R, i.e. a Canon EOS R body aimed a photography professionals and on the same tier as the EOS-1D X lineup, might be able to natively mount both RF and EF mount lenses.
Being able to mount both EF and RF mount lenses without using an adapter would be a killer feature. It’s not surprising it is rumored for the fabled EOS-1D X-like professional EOS R that might be announced next year, or in 2021 (all rumors).
As weird as this rumor may sound we give it some credit. While technically complex to implement it is surely not impossible, and we know Canon has the know how and the skills to do it. On other words: it’s feasible for Canon.
